I'm getting ready to make some alternative build platforms and the thickness is going to vary. I wanted an easy way to offset the Z-Axis stop without having to adjust the bolt every time I swap out a built platform.

When printed with a .1mm layer, these caps provide a range of offsets from .1mm to 5.8mm by simply dropping a cap over the head of the Z-Axis stop bolt. Make sure your bed is good and level before printing these. The different thicknesses are not identified in the model. I'm going to mark them with a Sharpie before I pull them off the built platform.
